How does data loss on NAS systems / RAID arrays occur?
Each data loss has its own story, but there are common scenarios that require data recovery from network storage.
- Human errors: Unfortunately, human error is a common cause when data is lost from a NAS. Data loss often happens accidentally due to reformatting, reinstallation, deleting or overwriting a volume.
- Power failure: NAS systems can become corrupt due to power failure, voltage fluctuations or overvoltage. RAID arrays (the storage inside the NAS) that have been in use for some time are particularly vulnerable, as voltage fluctuations can cause individual disks to be out of sync resulting in a degraded or failed RAID array.
- Overheating: Faulty cooling in the server room or an improper location in an office or at home can result in overheating and drive failures.
- Defective NAS controllers: Defective controllers can cause errors during reformats or rebuilds. Errors in the firmware or operating system caused by reconfiguring the memory can cause data loss.
- Mechanical errors: RAID systems are designed to compensate for the failure of one or more drives. As soon as a drive fails in a NAS/RAID, the remaining hard drives must compensate for the failure. Multiple drive failures can handicap the NAS/RAID to the point of complete failure.
- Natural disasters: Fire damage, water damage, pollution and other contamination can destroy a NAS in seconds. Rebuilding a contaminated system requires special knowledge and the ability to thoroughly clean individual drives and other components of the NAS. Only then can the data be restored by a logical rebuild. Ontrack has the technical proficiency to thoroughly clean and successfully restore heavily soiled media.
Emergency NAS Data Recovery Tips
What to do if you experience a NAS drive failure:
- If you hear unusual noises, you should shut down the system immediately.
- Validate your backup before replacing or updating hardware or software.
- Do not use RAID recovery software if there is a possibility of a hardware failure.
- Do not defragment drives that may be damaged.
- Do not rebuild and/or reinstall the original system. Do not restore a backup to the same volume/drives.
Emergency help for NAS devices.
Call our toll-free number at 855.652.2387 to find the fastest solution for your NAS recovery. We recover data for companies and individuals. No NAS recovery is too big or too small.
When you call we:
- Diagnose the cause of data loss and identify possible fault points
- Verify if Remote Data Recovery is possible
- Explain the data recovery process and the specifics for your individual case
Time is an important factor.
When it comes to business critical data, a NAS failure can cause huge financial damage.
Our experts always check the possibility of an Ontrack Remote Data Recovery (RDR), our fastest method of recovery. With this proprietary technology, the data is restored directly onto your server via a secure internet connection. With RDR, there is no need to dismantle the NAS server and no shipping necessary. All you need is an internet connection.
NAS Case Studies
Ransomware VBK Recoveries on Tape - Server & NAS Systems
Challenge
The attacked volume was originally also used to back up data to LTO8 tapes at regular intervals. Most of these backup tapes were also in the tape library at the time of the incident and were quickly formatted by the attackers. However, the customer was able to save an original unformatted tape with a fairly old backup date, which was then completely restored to the now empty Windows volume with a total of 6 TB. Only then was Ontrack commissioned to examine data recovery options. The HP server DL380 with the 55 3TB hard disks were transported to Ontrack in Böblingen Germany.
Solution
During the diagnosis, a large number of the searched VEEAM vbk files were successfully found on the Windows volume with Ontrack Tools and 27 records were extracted according to a priority list. The restore of the LTO8 tape partially overwrote some of the data sets and damaged the backup files.
Result
A large part of the data could still be repaired and extracted in several steps.
Later on, 19 significantly older LTO8 quick formatted tape backups were successfully recovered too.The attack also affected numerous European sub offices of the customer. Here were predominantly QNAP NAS systems in use which had stored virtual VMs under VMware, including backup VMs that were partially deleted or internally reformatted with another file system. Ontrack was also able to successfully restore complete backup data in 90% of the seven cases ordered.
